According to Kepler's first law, planets move in elliptical orbits. Why is that considered accelerated motion?
O a. Kepler's second law shows that a planet's speed changes due to radial acceleration. Planets also change direction as they move.
●
b. Planets are not perfect spheres and their masses are distributed unevenly within them. Kepler's third law shows that orbital periods change.

●
Cranets move not only around a sun but have their own rotation. This rotation causes radial acceleration. Kepler's first law shows that the distance between a planet and a sun changes too.
d. Kepler's second law shows that the area of space in the orbits is changing due to tangential acceleration.

Why did Newton conclude that some force had to pull the Moon toward Earth?
O
●
Oa. Newton had read the records of ancient astronomers and found out that the Moon had grown since ancient times. There had to be some force pulling the Moon toward Earth.
O b. Newton noticed an oscillation in the apparent progression of the lunar phases and concluded that there was some force that pulled the Moon toward Earth.
●
●
c. Newton knew that objects move in a straight line at a constant speed, unless acted upon by an outside force (Newton's first law). However, the Moon followed a curved path around Earth.
Od. When an apple hit Newton on the head, he understood that the very same force that had brought the apple crashing towards the ground also pulls the Moon toward Earth.
